Letters Patent No. 94,144, lated August 24, -1869.

The Schedule` referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, WILLIAM SPENCER, of Winslow, in t-he county of Pike, and ink the State of Indiana, have invented certain new and useful Improvements in Grain-separators; .and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this speciiication.

The nature of my invention consists in the construction of a grain-separator, by means of which thecheat, cockie, and all impurities in wheat can be readily and easily separated, as will hereafter be fully set forth and described.

The accompanying drawing represents a horizontal section viewl of my invention.

Letter A represents the frame, which may be of any desired shape or size, and which has its lower 'part divided into three or more separate' divisions, for the diiierent qualities of grain.

Revolving inside of the frame is the cylinder B, into which the grain is placed to be separated, and which is formed of wire, of different-sized screens, or `of wires and perforated plates together, the said plate being placed' upon the end of the screen, and having `the l openings through it larger than those in the screen.

Upon the outside o f the screen, extending from one end to the other, thereare a number of libs, c, which brace and strengthen it, and which allow the grain to move much more freely about, by being placed outside than in the screen.

At one end of the frame there is secured a hopper, D, having a spout leading inside of the cylinder, under its shaft, and is provided with a slide, so as to regulate the liow of' the grain, which is kept up without any shaking motion whatever,

AIn order to'control -the speed at which the grain is to move through the cylinder, the end/'of the'frame, on which Ithe hopper is attached, is pivoted between the legs, leaving the other end to movefreely up and down, so that the cylinder can be lowered to any desired angle, whereby the grain is made to moveslowly or rapidly, as may be desired. i

As the cylinder is kept constantly revolving, as the grain falls upon the screens, the cheat and cookie at once pass through the openings in the screen, and fallv into the first box n, and through the opening in the bottom, into a receptacle prepared for it.

A's the remainden of the grain passes on down, it has to pass over a second-sized screen, when the smaller grains drop through into the second box o, while the larger or No. 1 grain falls through the openings inV the plate G into the box e, while all larger articles pass on out of the cylinder, through the spout H, placed in the end of the screen.

Pivoted to one of the legs of the frame is the lever K, which has a small upright secured toits side, upon' the top of which the end of the frame rests.

Attached to the opposite end of the lever there is a .str-ap, (shown in dotted lines,) by means of which the frame is secured at any desired angle.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent is'- l. The fralne A, having two or more boxes formed in its bottom, when said frame is made adjustable by means of the lever K and its strap, substantially as shown and described. f A

2. The arrangement of the adjustable frame A, having two or more hoxesformed in its bottom, the revolving cylinder or drum B, hopper D, spent H, and lever K, all substantitlly as shown andA described.

In testimony that I claim the foregoing, Lhavehereunto setniy hand, thisA 14th day of June, 1869.

' vWILLIAM SPENCER.
